A crate resting on a horizontal floor (\muμs = 0.61, \muμk = 0.3 ) has a horizontal force F = 49 Newtons applied to the right. T

his applied force is the maximum possible force for which the crate does not begin to slide. If you applied this same force after the crate is already sliding, what would be the resulting acceleration (in meters/second2) ?

Answer:

a = 7.80 m/s²

Explanation:

given,

μs = 0.61

μk = 0.3

F = 49 N

we know,

F = μs m g

m = \dfrac{F}{\mu_s\ g}

m = \dfrac{49}{0.61 \times 9.81}

m = 8.19\ kg

now when the block start moving

F - F_k = F_{net}

F - F_k = ma

a = \dfrac{F}{m}-\dfrac{F_k}{m}

a = \dfrac{F}{m}-\dfrac{\mu_k m g}{m}

a = \dfrac{88}{8.19}-0.3\times 9.8

a = 7.80 m/s²

Write down the principal of lever​
pashok25 [27]

Answer:

See the explanation below.

Explanation:

A lever is a simple machine that changes the magnitude and direction of the force applied to move an object. Minimizes the force needed to lift the object.

By means of the following image, we can see the principle of operation of a lever.

The load can be moved thanks to the force multiplied by the distance to the fulcrum.

What kind of energy change occurs when a battery is operating a remote control toy?
solniwko [45]

Answer:

Explanation:

The correct answer is option C.

When the battery is operating a remote control toy the energy is converted from potential energy to the kinetic energy.

A battery stores electrical potential from the chemical reaction.

When the circuit is connected to the potential energy of the battery helps in the movement of the toy.

The energy produced by the movement of the control toy is kinetic energy.

Hence, we can say that Potential energy is changed to kinetic energy
